Hi Alban, If I do: select * from SourceCategory pgAdmin gives me an error: ERROR: relation "sourcecategory" does not exist If I do: select * from "SourceCategory" It works OK. As Richard mentioned, it's because table was probably created with CREATE TABLE "SourceCategory". I was not sure about this because I had no control over creating the tables.

Postgres understands that fine, why do you want to quote those identifiers? Maybe your application code is case-sensitive with regards to column (and maybe table) names?
